Common Reasons  For A Toilet To Run Randomly

1. SEDIMENT BUILD-UP

Accumulation of minerals from hard water prevents the flapper from sealing completely. If enough water leaks out of the tank, then the refilling mechanism is triggered resulting in a “phantom flush.”

2. Improperly Installed  Flapper Chain

If the chain is not attached correctly (or if it is too long or too short), this can hinder the flapper’s ability to completely seal the hole, thus resulting in a randomly running toilet.

3. A LEAK IN THE  FILL VALVE

If this valve is damaged or leaking, water will continue to fill-up in the tank, causing the toilet to keep running.

4. NOT ENOUGH  (OR TOO MUCH) WATER

If the water level in the tank is not accurate, this could cause a toilet to run randomly.The water should rest 1 to 2 inches (or 2.5 to 5 cm) below the fill valve.If it is higher or lower than this amount, the off-balance will likely result in a "phantom flush".

5. A FAULTY TOILET HANDLE

By not returning to the original position after flushing, the handle can let more water into the tank than necessary.
